[llvm-dev] TableGen crash when building LLVM with EXPENSIVE_CHECKS enabled

[llvm-dev] TableGen crash when building LLVM with EXPENSIVE_CHECKS enabled
I briefly dug into this and I can reproduce it, the issue appears to be the implementation of std::shuffle (which is called by llvm::sort with expensive checks). Sounds like you should file a bug against libstdc++.

[llvm-dev] TableGen crash when building LLVM with EXPENSIVE_CHECKS enabled
This looks like https://bugs.llvm.org/show_bug.cgi?id=37652 to me. I added a workaround ( https://github.com/CTSRD-CHERI/llvm-project/commit/a7e68c6baf9967cfb288ca6c53c43b29581d27d8) to our fork but never got around to submitting a review. If adding a copy of the libc++ implementation as llvm::shuffle seems like a valid approach I'll upload the patch to phabricator.
